Of Course, but...
There are only so many ways that a network engineer, for example, can deploy network access. And even if you did get creative with your network design, it's possible that the person coming in after you might not appreciate your "creativity". As a network admin, I've learned that the best policy is K.I.S.S.
So for some roles, the scope of creativity is limited. For developers however, it is (and should be) limitless. I've been blessed with a job that allows me to develop new tools to solve old problems given a variety of different tools. I've developed add-in applications for Outlook that process data inside mail attachments, developed an on-call rotation management app using MMC 3.0, and a couple of other things. The best thing for me is that these were MY ideas. Even better, they work, and my users have praised my efforts. Situations like these are win (managers) - win (users) - win (me).
